Business
CAELUM Co., Ltd. is a South Korea-based industrial manufacturing company engaged in the production of aerospace engine components and specialized equipment for green energy, liquefied natural gas (LNG), and petrochemical plants. Founded in 2009 and headquartered in Busan, South Korea, the company operates across two principal business segments: Aerospace and Energy Plants. In its Energy Plants segment, CAELUM designs, fabricates, and supplies heavy industrial equipment and power generation components, including shell and tube heat exchangers; air-cooled heat exchangers; high-pressure vessels; distillation towers and columns; modular process skids; heat recovery steam generators (HRSG); geothermal power generation systems; pre-fabricated piping spools; and finning machinery. In its Aerospace segment, the company manufactures high-precision, high-temperature aircraft engine components, utilizing specialized National Aerospace and Defense Contractors Accreditation Program (NADCAP) certified processes including electrical discharge machining (EDM), heat treatment (HT), non-destructive testing (NDT), and welding (WLD) to serve aerospace original equipment manufacturers, including Safran and Hanwha Aerospace. The company distributes its products and services to global energy plant developers, engineering, procurement, and construction (EPC) contractors, and commercial and defense aviation clients across Asia, Europe, and North America. In recent major strategic developments, the company rebranded from EWK Inc. to CAELUM Co., Ltd. to drive its dual-track growth strategy combining green energy and aerospace defense. Following its initial acquisition of aircraft engine parts manufacturer Hana ITM Co., Ltd., CAELUM completed a full statutory absorption merger of Hana ITM in March 2026, integrating the enterprise directly into its internal Aerospace Division to optimize manufacturing synergies and expand long-term global supply contracts. Furthermore, CAELUM operates under the parentage of Green Tech System Co., Ltd. and continues to evaluate strategic diversification into electric vehicle charging systems and advanced clean-technology infrastructure.
